Re: [Mingw-w64-public] [PATCH mingw-w64] Add include/iscygtty.c

There are files that were catenated.

Running curses in conemu should be possible with
https://conemu.github.io/en/CygwinMsysConnector.html

But even then, the iscygtty() is supposed to check
whether it is present with a mintty-like stdin, and nothing else.

all: test

a.exe: main.c
$(CC) -Wall -Wextra main.c -lntdll

two cases :

1) pipe redirection : mintty and therefore cygwin (>= 1.8) terminal
and MSYS2 terminal (as the 2 latters are based on mintty)
2) MSYS1 and CMD console

ConEmu is a specific case as, if i'm not mistaken, it can switch from
one redirection to the other one

PS: i've also replied to the mingw-w64 ML, Mihail, maybe you should
send again the files to the ML

hello

just call GetConsoleMode() and check its result to know if the
redirection is with a pipe or a console handle

[Mingw-w64-public] [PATCH mingw-w64] Add include/iscygtty.c

2016-11-09 Thread Mihail Konev 
Applications now could call iscygtty(STDIN_FILENO)
in order to detect whether they are running from
Cygwin/MSys terminal.

Without that, they have no choice but to think that
stdin is redirected from a named pipe.
